From what I have heard and seen, the official HD pack is not that spectacular. If you're planning on texture pack mods, I see no reason to install the official one. Most of it's content will be overwritten by the mods anyway. As for texture mods themselves: I could not play anymore without Skyrim HD (lite) and aMidianBorn. You might also want to check out Vuurt's Flora Overhaul (Basic) but then you'd better have 2GB video ram.

If you want more, I suggest you look up STEP 2.2.6. It's a project that tries to compile Skyrim mods into a guide format. They have many suggestions that you would never find yourself. It's what I followed. Check my Steam profile for some screenshots of what mine looks like now!

Pick up the full version of skyrim 2k textures (4096x4096 is awesome!!!), as well as Bethesda's official texture pack (gives most textures- 1024x1024, some, however are 2048x2048). This gives an extra edge as it does armour to the same Resolution as Amidianborn, as well as some textures that 2k doesn't do (dlc textures). Install this first, than 2k textures. Improved NPC clothing is amazing too (4k- 4096x4096 textures). If you list your specs, i can determine if you can use these. I also reccomend Project Reality-climates of tamriel, and Project Enb, although most half decent gaming pcs only run with 25-30 fps with all these mods. I get 70 fps outside, and 120 outdoors, but it depends on your system, as i have a GTX 780...

I just discovred how NMM is pure garbage, I don't understand how it got so pupolar.

It's my experience also. In my case it just didn't work, and support seems to be a bit lacking and slow. I tried Skyrim Mod Manager instead, and I couldn't be happier. I find it easy to use, and it has virtual storage that makes installing _and_ removing mods a blast. Wyre Bash is another popular alternative but I haven't tried that myself.
